Should the pipe characteristic table include a welding joint coefficient?
You’re not a material science expert or a welding specialist – who gives you the qualifications and confidence to write about this? ? The characteristic table indicates the welding ratio! ! ! Inspection qualification grade! ! ! It’s also frustrating to see so many people write about the testing level (20801).
In the pipe characteristic table format specified in HG/T 20519, there is no column for the welding joint coefficient. When I carry out preliminary design work, some organizations include this welding joint coefficient, and it is further divided into longitudinal and circumferential types; where can I find the welding joint coefficient for circumferential joints?
Oh, the units are different; our design process includes detailed design and manufacturing design
The characteristic table specifies the radiation inspection ratio and the acceptable inspection grade.
